Cushion pad structure for a carpet installation tool

Abstract

The cushion pad structure of the carpet installation tool comprises a rubber covering layer, a rubber foam body and an assembly board. The foam body is disposed in the covering layer. The foam body comprises a thrust face, which has a plurality of the first holes with at least a predetermined depth. The thrust face is designed so that a technician's knee or heel receives less reaction force from the impulse imparted due to the plurality of the first holes and softened hardness. Under the impulse force, the hardness of the advance gradually cushioning structure increases its hardness slowly and generates a maximum hardness at a proper position that may be experimentally determined, efficiently transferring the maximum impulse force to the carpet installation tool. The carpet installation tool therefore provides protection for the technician's knee and ankle joints, and efficiently transfers the impulse force.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cushion pad structure for an installation tool, and more particularly, to a cushion pad structure for a carpet installation tool.[0003]2. Description of the Related Art[0004]Generally, carpets or rugs lying on a floor need to be tightened and smoothed over the surface of the floor, and should not exhibit wrinkles or raised so as to avoid trip and fall type accidents or injuries.[0005]Additionally, many carpets and rugs present pattern matching problems, which may arise from the pattern in the carpet or rug itself, or with another pattern in the environment, such as patterns on walls or furniture appear uncoordinated. However, while it is sometimes impossible to re-install the entire carpet, it may be possible to make sectional adjustments.[0006]When carpet installation is being performed along the edges of the walls or in corners, since the technician is standing on the carpet, he or s...

AI Technical Summary

Benefits of technology

The cushion pad structure effectively protects knee and ankle joints while efficiently transferring impulse force, minimizing injury risk and enhancing installation tool performance.

Problems solved by technology

Additionally, many carpets and rugs present pattern matching problems, which may arise from the pattern in the carpet or rug itself, or with another pattern in the environment, such as patterns on walls or furniture appear uncoordinated.

However, while it is sometimes impossible to re-install the entire carpet, it may be possible to make sectional adjustments.

Additional, the carpet installation tool may be used very frequently by the technician, which might cause temporary or sustained or even permanent chronic injury to the knee or ankle joints of the technician.

Therefore, there are many technicians in this field that have stopped working because of injuries to knee or ankle joints.

Softer cushion pads provide better protection for knee and ankle joints, but do not efficiently transfer the impulse force; on the other hand, harder cushion pads directly and efficiently transfer the impulse force, but they also create larger reaction forces to knee and ankle joints, which cause unnecessary injury.
